[NTLUG:Discuss] Wireless Home Network -- 2.4GHz band

[Burton M. Strauss III]

Actually, it's BOTH.

Using channels other than 1, 6 and 11 is perfectly proper and legal.  It's
just that is may cause more interference.  For example using 9 might degrade
another user on both 6 and 11.

Remember, the ISM (Industrial/Scientific/Medical) band has two simple rules:

1. Eat anything blasted at you.
2. Don't blast anyone else.

Beyond that, it's a free-for-all.

In the case of WiFi, they defined a standard, but that still has to live
within the ISM 2.4GHz band rules.  The WiFi standard defines 11 channels of
which three do not overlap.

But 2.4GHz cordless phones can use any part of the ISM spectrum they dang
please.

So you have THREE common sources of interference to get around

1. Microware oven
2. Other WiFi users
3. Other ISM 2.4 users such as your cordless phone.
